Ok what am I doing wrong? Pulled apart the reg to see if anything is wrong as I can't get it to let my S5 shoot up to velocity. Everything is fine, o-rings, spring, piston, poppit, poppit spring, everything. Cleaned and re-lubed and still causing my marker to shoot below 200. Turning it in to increase pressure isn't causing any changes

"But Donut, are you sure it's the reg? what about the springing in the lower tube? Maybe your internals are bad?"

Same settings, swapped out the S5 reg with another reg I have up to speed. Shot @ 315fps.

I don't want my reg piston to end up like noclue's if I keep turning it in with no result
